"They returned to China with the assistance of (the) Chinese Embassy to Vietnam," China's Foreign Ministry said on Sunday in a statement.
The staff members, from the China 19th Metallurgical Corporation (MCC19), arrived at the Chengdu Shuangliu International Airport in southwest China's Sichuan Province.
Those evacuated early on Sunday included 16 critically hurt Chinese nationals, according to a state-run news agency.
The Chinese government is arranging for chartered plane and vessel to take back others wanting to leave following the violence that spread to 22 of Vietnam's 63 provinces in the last week.
Beijing has also advised its nationals against travelling to Vietnam.
China says two of its nationals were killed in the violence and more than 100 others injured while the official death toll has been put at 21.
An iron and steel complex in Ha Tinh Province of Vietnam, invested by Taipei-based Formosa Plastics Group, was badly hit in the riots.
China and Vietnam are locked in a duel after Beijing deployed an oil rig off the disputed waters in South China Sea on May 1. The naval vessels of both the countries have rammed into each other hundreds of times since then.
The dispute is part of a wider row between China and a number of south-east Asian countries including Vietnam, the Philippines, Malaysia and Brunei.
But Vietnamese authorities, which have occasionally allowed anti-China protests, have said that it will prevent further outbursts that stemmed from the controversial deployment.
An alliance of 20 vocal Vietnamese NGOs has called for fresh protests in the capital Hanoi, the southern economic hub of Ho Chi Minh City, and other areas against China's ‘aggressive actions’ in the South China Sea. It, however, urged participants to remain peaceful.
The alliance, believed to have played a role in stirring the protests, comprises largely of anti-government outfits.
On Thursday, Chinese Vice Foreign Minister Liu Zhenmin had summoned Vietnamese Ambassador to China, Nguyen Van Tho, and lodged solemn representation.
Liu demanded Vietnam take forceful measures to stop criminal activities and punish the perpetrators, and to ensure the safety of the lives and property of Chinese nationals there.
